...but I found another earthworm crawling around on the tile. Watching it inch around between the cracks as I took a shower last night made me nautious, and made me wonder; Where do they come from? How can they get into my bathroom? Are there latent annelid eggs spawning from the grout? Do my students sneak into my bathroom and plant them there? My guess is that they crawl up the drains, or that there is some small undetected crack that leads inside. About 4 months ago I found a millipede in my bath. I ignored it, and it died, and had a huge clutch of babies, which hatched. I found baby millipedes crawling all over the place for the following months, and stopped counting after 20. My advice: kill the mother and the eggs and save yourself the trouble of killing a lot of tiny monsters! Hahaha, the shiitake growing in my Sabado Tarde apartment shower no longer seems SO disgusting (It was a huge sucker!).
